Causes of oil leakage

Existence of holes in the oil seals Since oil cannot expand sufficiently to seal all the space in oil

filters, oil may leak from the engine easily. When additives are added to seal these holes, it spill even more due to excessive expansion.

Damaged valve gasket Old vehicles and those that travel long distances are

vulnerable to this condition. The wearing out of the gasket allows accumulation of sludge and the result is increase in pressure at those points which consequently lead to oil leakages. The effect is normally severe on poor roads with debris and large rocks.

Damaged oil drain plugs This occurs when threads are misaligned, worn-out or get

dirty. This may loosen the oil drain plug hence allow the leakage of oil from the oil pan through the underside.

Worn-out camshaft Creates spaces therefore allowing oil to get into the timing

belts .When timing belts are not correctly replaced, they can cause oil leakage.
